摘要： A method and apparatus for performing a handover are disclosed. An Internet protocol (IP) multimedia subsystem (IMS) client registers with an IMS network and establishes a media independent handover (MIH) session with an MIH application server using a session initiation protocol (SIP). The IMS client establishes a session for IP-based service, (e.g., voice over IP (VoIP)), with a communication peer using an SIP. MIH messages are exchanged for handover with the MIH application server over IP. After handover, the session is resumed. A serving call session control function (S-CSCF) triggers the MIH application server based on a string "MIH services" and a unique identifier included in an INVITE request. The IMS client may send a REFER request to the MIH application server after the handover to resume the session. Alternatively, the IMS client may send a RE-INVITE request to the MIH application server and the communication peer.
摘要翻译：公开了一种用于执行切换的方法和设备。互联网协议（IP）多媒体子系统（IMS）客户端向IMS网络注册，并使用会话发起协议（SIP）与MIH应用服务器建立媒体无关切换（MIH）会话。 IMS客户端使用SIP为通信对端建立基于IP的服务的会话（例如，IP语音（VoIP））。 MIH消息通过IP与MIH应用服务器进行交换。切换后，会话恢复。服务呼叫会话控制功能（S-CSCF）基于包括在INVITE请求中的字符串“MIH服务”和唯一标识符来触发MIH应用服务器。 IMS客户端可以在切换之后向MIH应用服务器发送REFER请求以恢复会话。或者，IMS客户端可以向MIH应用服务器和通信对端发送RE-INVITE请求。

摘要： The present invention modifies existing media independent handover (MIH) function (MIHF) frame format as defined by the IEEE 802.21 standard. In one embodiment, the variable load of the MIHF frame is modified to eliminate the MIHF variable header by defining the MIHF identification (ID) field and the session ID field as fixed fields in the MIHF fixed header. Thus, the MIHF variable load is only made up of the MIHF payload. In another embodiment, a field such as an information element (IE), a header, or MIH service data such as a command or an event, is represented by a type field, a length field and a value field (TLV). The length of the value field is exactly 128 octets, and the length field only occupies one octet.
摘要翻译：本发明修改了由IEEE 802.21标准定义的现有媒体独立切换（MIH）功能（MIHF）帧格式。在一个实施例中，MIHF帧的可变负载被修改以通过将MIHF标识（ID）字段和会话ID字段定义为MIHF固定头部中的固定字段来消除MIHF可变头。因此，MIHF可变负载仅由MIHF有效载荷组成。在另一个实施例中，诸如信息元素（IE），头部或诸如命令或事件的MIH服务数据之类的字段由类型字段，长度字段和值字段（TLV）表示。值字段的长度恰好是128个八位位组，长度字段只占用一个八位字节。

摘要： The present invention integrates resource allocation between time division duplex (TDD) and frequency division duplex (FDD) in wireless communication systems (200). A radio network controller (RNC) (206, 210) receives a radio access bearer (RAB) request from a core network or a wireless receive/transmit unit. The RNC utilizes a TDD-FDD selector (204, 208) to assign radio resources in response to the request. The TDD-FDD selector evaluates various parameters regarding the received RAB request and determines whether it is preferable to assign TDD resources or FDD resources and whether such resources are currently available. Once resources are assigned, system conditions are evaluated to determine whether optimizations may be made to a current resource allocation.

摘要： A method for battery conservation in a wireless communication system begins with requesting a battery level measurement from a wireless transmit/receive unit (WTRU) by a radio network controller (RNC). The battery level is measured at the WTRU and is reported to the RNC. The battery level measurement is stored in the RNC, where it can be accessed by radio resource management (RRM) procedures. The battery level measurement is applied to the RRM procedures by making adjustments to the procedures based on the battery level measurement, whereby the battery of the WTRU is conserved.

摘要： A mobile communication system (10) includes cell segments (14) each associated with a base station (18). The base station includes transceivers (25, 27) capable of communicating over two sets of carriers (26, 28). A first set of carriers (26) carry circuit-switched traffic, while the second set of carriers (28) carry packet-switched data. Co-channel interference measurements are made by mobile units (20) or by a serving base station (18) in each cell segment (14) during communications of active bursts of traffic or control signaling. Such bursts may include a training sequence that is used by the measuring device to recreate a burst without interference contributions. Co-channel interference is then determined based on the recreated bursts and the received bursts. Multiple interference values may be derived and applied to an averaging filter to calculate the final interference contribution value.
